We're dividing 14349107 by 784 
The aim is to understand the frequency of 784 in 14349107.

Advancing to step 1:
The number 784 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 784

Going ahead to step 2:
When dividing 14 by 784, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 784

Advancing to step 3:
When dividing 143 by 784, we get 0 with a remainder of 143.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 143 after subtracting 0 from 143.
Grab the next digit (4) from the dividend, add it to 143, then carry on: 1434 / 784

Advancing to step 4:
When dividing 1434 by 784, we get 1 with a remainder of 650.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 784 from 1434 and we're left with 650.
Bring next digit (9) of the dividend behind the 650 and repeat the process: 6509 / 784

On to step 5:
784 goes into 6509 8 times with a remainder of 237.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 6272 from 6509 and we're left with 237.
Append the next digit (1) from the dividend to 237 and continue with: 2371 / 784

Advancing to step 6:
When dividing 2371 by 784, we get 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we take 2352 away from 2371, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 784

Moving on to step 7:
784 can be fit into 190 0 times, resulting in a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 1830.0
If we take 0 away from 190, we end up with 190.
Take the next digit (7) from the dividend and append it to 190, then repeat: 1907 / 784

On to step 8:
1907 divided by 784 is 2 with a remainder of 339.
Record the quotient 2 as the next digit in the result. 
Result so far: 18302.0
The remainder is 339 after subtracting 1568 from 1907.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 9:
3390 divided by 784 is 4 with a remainder of 254.
The number 4 becomes the next digit in our result. 
Result so far: 18302.4
The remainder is 254 after subtracting 3136 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 10:
784 can be fit into 2540 3 times, resulting in a remainder of 188.
Write down 3 as next digit of the result. 
Result so far: 18302.43
If we subtract 2352 from 2540, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
784 can be fit into 1880 2 times, resulting in a remainder of 312.
The number 2 becomes the next digit in our result. 
Result so far: 18302.432
If we take 1568 away from 1880, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 12:
3120 divided by 784 is 3 with a remainder of 768.
Put 3 as the next digit of the answer. 
Result so far: 18302.4323
Subtracting 2352 from 3120 leaves us with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Step 13:
If we divide 7680 by 784, we get 9 and a remainder of 624.
Record the quotient 9 as the next digit in the result. 
Result so far: 18302.43239
Deduct 7056 from 7680 and we're left with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 14:
If we divide 6240 by 784, we get 7 and a remainder of 752.
The next digit of our result is 7. 
Result so far: 18302.432397
Subtracting 5488 from 6240 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Going ahead to step 15:
784 goes into 7520 9 times with a remainder of 464.
Write down 9 as next digit of the result. 
Result so far: 18302.4323979
If we take 7056 away from 7520, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 16:
The number 784 fits into 4640 5 times, leaving a remainder of 720.
The next digit of our result is 5. 
Result so far: 18302.43239795
Deduct 3920 from 4640 and we're left with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

After the division, we end up with 18302.43239795 and a remainder of 7.2e-07.
